Sound Waves Essay

Sound Light and Ocean Biochemical Processes

Propagation of sound and the transmission of light within water

Sound

All sounds come from vibrations causing sound waves. Sound waves will travel better through solids and liquids than they will gas.

“Sound or acoustic energy involves the actual vibration of the actual material through which it passes and thus, in general, propagates best through solids and liquids, less well in gasses and not at all in a vacuum” (Wright et al., 1995, p. 70)

Objects in water vibrate and cause sound-pressure waves that compress and decompress water molecules as the waves travels through the water. Sound waves will radiate at equal energy in all directions from source, in the form of compression waves.

Sound waves are measured in frequency which can be defined as the number of pressure waves passing a fixed point in a set time. “The velocity of sound in seawater is approximately 1500ms”(Wright et al., 1995, p. 71) Wavelength is the distance

(Nieukirk, 2013) peaks of a specific sound wave. The height of the wavelength measures loudness or amplitude.

Frequency of sound waves is measured in

This part of photosynthesis takes part in the stroma located in the chloroplast. The Calvin Cycle involves the reduction of carbon dioxide and require hydrogen from NADPH and ATP for energy.

The first part of the Calvin Cycle a 5 carbon compound called ribulose bisphosphate will combine with a 6 carbon compound the compound however is unstable and will split into 2 molecules of a 3 carbon compound, this is called glycerate 3 phosphate. This reaction is catalyzed by the enzyme ribulose bisphosphate carboxylase. glycerate
